My project is to test the Pseudomonas antibiotic's resistant capabilities on different kind antibiotics ( artificial vs herbal). However, i can't find a way to come up with data(numbers) for graph and chart. Is there a way to count the dead and alive bacteria on the petri dish after t antibiotic had been applied?

In addition, It is difficult to obtain antibiotic for human so i decided to us antibiotic for animal as a substitute. So is there any different between antibiotic for human and animal?

This is a really great project idea and here is a source that will give you measurable results that you need for your results section of your science project:

http://www.hhmi.org/biointeractive/dise ... vities.pdfThe antibiotic resistance test involves measuring the zone of inhibition in millimeters around an antibiotic disc growing on a lawn of bacteria. The protocol above does not describe how to prepare the culture, however, you should use freshly grown broth cultures not more than 12 hours old.

Here is a project idea from the Science Buddies website that includes other helpful information such as a link to the Microbiology Techniques and Troubleshooting and SRC approval, which you may need for this project:
